18QHTF21-83.333333-OE

Overview

The 18QHTF21-83.333333-OE is a quartz crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 83.333333 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications. The component supports standard clock signal generation requirements within its specified operating parameters.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power control
• Surface-mount 4-SMD no-lead package design

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the exact frequency tolerance and load capacitance specifications against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues or potential damage during operation.

Selection Notes

Select this component when a precise 83.333333 MHz clock source is required with low-voltage operation. The LVCMOS output is suitable for standard digital logic families. Consider the enable pin requirement if dynamic power management is necessary. The small form factor makes it appropriate for space-constrained PCB layouts where surface-mount technology is preferred over through-hole alternatives.

Part Context

This oscillator belongs to the Mercury Electronic series of quartz-based frequency control products. The manufacturer has extensive experience in producing quartz crystals and oscillators.
